Age as a Barrier to Surgical Stabilization of Rib Fractures in Patients with Flail Chest.

INTRODUCTION: Although randomized trials demonstrate a benefit to surgical stabilization of rib fractures (SSRF), SSRF is rarely performed. We hypothesized older patients were less likely to receive SSRF nationally. METHODS: The 2016 National Inpatient Sample was used to identify adults with flail chest. Comorbidities and receipt of SSRF were categorized by ICD-10 code. Univariable testing and Multivariable regression were performed to determine the association of demographic characteristics and comorbidities to receipt of SSRF. RESULTS: 1021 patients with flail chest were identified, including 244 (23.9%) who received SSRF. Patients ≥70 years were less likely to receive SSRF. (<70 yrs 201/774 [26.0%] vs ≥70 43/247 [17.4%], P = .006) and had higher risk of death (<70 yrs 39/774 [5.0%] vs ≥70 33/247 [13.4%], P < .001) In multivariable modeling, only age ≥70 years was associated with SSRF (OR .591, P = .005). CONCLUSION: Despite guideline-based support of SSRF in flail chest, SSRF is performed in <25% of patients. Age ≥70 years is associated with lower rate of SSRF and higher risk of death. Future study should examine barriers to SSRF in older patients.

Surgical Repair vs Stent for Esophageal Perforation: A Multi-institutional Database Analysis.

BACKGROUND: Endoscopic esophageal stenting is used as an alternative to surgical repair for esophageal perforation. Multi-institutional studies supporting stenting are lacking. The purpose of this study was to compare the outcomes of surgical repair and esophageal stenting in patients with esophageal perforation using a nationally representative database. We hypothesized that mortality between these approaches would not be different. METHODS: The Premier Healthcare Database was used to compare adult inpatients with esophageal perforation receiving either surgical repair or esophageal stenting from 2009 to 2019. Patients receiving intervention ≤7 days of admission were included in the analysis. Patients receiving both stent and repair on the same day were excluded. The composite outcome of interest was death or discharge to hospice. Logistic regression was used to evaluate independent predictors of death or hospice, adjusting for comorbidities. RESULTS: There were 2543 patients with esophageal perforation identified who received repair (1314 [51.7%]) or stenting (1229 [48.3%]). Stenting increased from 7.0% in 2009 to 78.1% in 2019. Patients receiving repair were more likely to be female and White and had fewer Elixhauser comorbidities. Death or discharge to hospice was more common after stent (134/1314 [10.2%] repair vs 199/1229 [16.2%] stent; P < .001); however, after adjustment for comorbidities, logistic regression suggested that death or hospice discharge was similar between approaches (stent vs repair: odds ratio, 1.074; 95% CI, 0.81-1.42; P = .622). Hospital length of stay was shorter after stenting (stent vs repair coefficient, -4.09; P < .001). CONCLUSIONS: In patients with esophageal perforation, the odds for death or discharge to hospice were similar for esophageal stenting compared with surgical repair.

Comparing Thoracoscopic and Robotic Lobectomy Using a Nationally Representative Database.

BACKGROUND: Studies of robotic lobectomy (Robot-L) have been performed using data from high-volume, specialty centers which may not be generalizable. The purpose of this study was to compare mortality, length of stay (LOS), and cost between Robot-L and thoracoscopic lobectomy (VATS-L) using a nationally representative database hypothesizing they would be similar. METHODS: The Premier Healthcare Database was used to identify patients receiving elective lobectomy for lung cancer from 2009 to 2019. Patients were categorized as receiving Robot-L or VATS-L using ICD-9/10 codes. Survey methodology and patient level weighting were used to correct for sampling error and estimation of a nationally representative sample. A propensity match analysis was performed to reduce bias between the groups. Primary outcome of interest was in-hospital mortality. Secondary outcomes were LOS and patient charges. RESULTS: Among 62 698 patients, 19 506 (31.1%) underwent Robot-L and 43 192 (68.9%) underwent VATS-L. Differences between the groups included age, race, comorbidities, and insurance type. A propensity matched cohort demonstrated similar in-hospital mortality for Robot-L and VATS-L (.9% vs .9%, respectively, P = .91). Patients who underwent Robot-L had a shorter LOS (4 vs 5d, respectively, P < .001) but higher patient charges (90 593.0 vs 72 733.3 USD, respectively, P < .001). CONCLUSIONS: In a nationally representative database, Robot-L and VATS-L had similar mortality. Although Robot-L was associated with shorter hospitalization, it was also associated with excess charges of almost $20,000. As Robot-L is now the most common approach for lobectomy in the U.S., further study into the cost and benefit of robotic surgery is warranted.

Robotic Approach Has Improved Outcomes for Minimally Invasive Resection of Mediastinal Tumors.

BACKGROUND: The optimal minimally invasive surgical approach to mediastinal tumors is unknown. There are limited reports comparing the outcomes of resection with robotic-assisted thoracoscopic surgery (RATS) and video-assisted thoracoscopic surgery (VATS) surgery. We hypothesized that patients who underwent RATS would have improved outcomes. METHODS: The National Cancer Database was queried for all patients who underwent a minimally invasive surgical approach for any mediastinal tumor from 2010 to 2016. Patients were determined to have an adverse composite outcome if they had any of the adverse perioperative outcomes: conversion to open procedure, 90-day mortality, 30-day readmission, and positive pathologic margins. Secondary outcomes of interest were length of stay and overall survival. Multivariable logistic regression was used to assess likelihood of having a composite adverse outcome based on surgical approach. RESULTS: The study included 856 patients: 402 (47%) underwent VATS and 454 (53%) underwent RATS. RATS resections were associated with fewer conversions (4.9% vs 14.7%, P < .001), fewer positive margins (24.3% vs 31.6%, P = .02), shorter length of stay (3.8 days vs 4.3 days, P = .01), and fewer composite adverse events (36.7% vs 51.3%, P < .001). Multivariate analysis showed RATS (odds ratio, 0.44; P < .001) was independently associated with a decreased likelihood of a composite adverse outcome, even among tumors exceeding 4 cm (odds ratio, 0.45; P = .001). Overall survival was similar between the 2 groups. CONCLUSIONS: Among patients who underwent a minimally invasive surgical approach for a mediastinal tumor, RATS had fewer adverse outcomes than VATS, even for tumors 4 cm or larger. These data suggests that RATS may be the preferred technique for patients who are candidates for minimally invasive resection of mediastinal tumors.

Are We Underestimating the Morbidity of Single Rib Fractures?

PURPOSE: Previous studies suggest that patients with multiple rib fractures have poor outcomes, but it is unknown how isolated single rib fractures (SRF) are associated with morbidity or mortality. We hypothesized that patients with poor outcomes after SRF can be identified by demographics and comorbidities. The purpose of this study was to model adverse outcome after single rib fractures. MATERIALS AND METHODS: We used the 2016 National Inpatient Sample to identify patients with SRF associated with blunt trauma using ICD-10 coding. Comorbidities and abbreviated injury score (AIS) were also extracted. Patients with non-chest trauma were excluded. The primary outcome was an adverse composite outcome of death, pneumonia, tracheostomy, or hospitalization longer than twelve days. One-third of the cohort was reserved for validation. Backward selection multivariable modeling identified factors associated with adverse composite outcome. The model was used to create a nomogram to predict adverse composite outcome. The nomogram was then tested using the validation cohort. RESULTS: 2,398 patients with isolated SRF were divided into training (n = 1,598) and validation sets (n = 800). The average age was 69 and the majority were male (66%) and received care at academic institutions (61.6%). The adverse composite outcome occurred in 20.8%: 61 deaths (2.5%), 67 tracheostomies (2.8%), 319 pneumonias (13.3%), and 165 patients with hospital length of stay greater than twelve days (6.9%). Results of stepwise multivariable modeling had a C-statistic of 0.700. The multivariable model was used to create a nomogram which had a c-statistic of 0.672 in the validation cohort. CONCLUSION: 20% of isolated SRF patients had an adverse outcome. Demographics and comorbidities can be used to identify and triage high-risk patients for specialized care and proper counseling.

Palliative Surgery Outcomes for Patients with Esophageal Cancer: An National Cancer Database Analysis.

INTRODUCTION: Many patients with esophageal cancer are not candidates for surgical resection with curative intent, given the advanced stage of disease at presentation. Palliative surgery is one treatment option, but relative survival of palliative surgery has not been described. This study aims to describe the outcomes of palliative surgery in patients with esophageal cancer. METHODS: We used the National Cancer Database to identify patients with esophageal cancer who received palliative surgery or non-surgical palliation-which consisted of palliative radiation and palliative chemotherapy without any surgery. The outcome of interest was overall survival. Characteristics of patients were compared between the palliative surgery group and the non-surgical group using rank sum test or chi square test. Survival differences between groups were compared using Kaplan Meier estimate and log rank test, and Cox proportional hazards model. RESULTS: A total of 14,589 patients were included in the analysis, including 2,812 (19.2%) receiving palliative surgery and 11,777 (80.7%) receiving non-surgical palliation (6,512 palliative radiation and 5,265 palliative chemotherapy). Median overall survival in palliative surgery patients was 5.5 mo, shorter than non-surgical palliation (6.4 mo, P = 0.004). However, when correcting for age, sex, nodal status, metastases, Charlson score, histology, academic center, and private insurance, there was no difference in survival between palliative surgery and non-surgical palliation in Cox proportional hazard modeling (HR 1.03 (0.975-1.090), P = 0.281). CONCLUSIONS: Palliative surgery in advanced esophageal cancer is associated with poor overall survival but is similar to other palliative modalities. Palliative Surgery for esophageal cancer patients should be used sparingly given these poor outcomes.

Concurrent diagnosis of anxiety increases postoperative length of stay among patients receiving esophagectomy for esophageal cancer.

OBJECTIVE: Psychiatric comorbidities disproportionately affect patients with cancer. While identified risk factors for prolonged length of stay (LOS) after esophagectomy are primarily medical comorbidities, the impact of psychiatric comorbidities on perioperative outcomes is unclear. We hypothesized that psychiatric comorbidities would prolong LOS in patients with esophageal cancer. METHODS: The 2016 National Inpatient Sample (NIS) was used to identify patients with esophageal cancer receiving esophagectomy. Concurrent psychiatric illness was categorized using Clinical Classifications Software Refined for ICD-10, creating 34 psychiatric diagnosis groups (PDGs). Only PDGs with >1% prevalence in the cohort were included in the analysis. The outcome of interest was hospital LOS. Bivariable testing was performed to determine the association of PDGs and demographic factors on LOS using rank sum test. Multivariable regression analysis was performed using backward selection from bivariable testing (α ≤ 0.05). RESULTS: We identified 1,730 patients who underwent esophagectomy for esophageal cancer in the 2016 NIS. The median LOS was 8 days (IQR 5-12). In bivariable testing, a concurrent diagnosis of anxiety was the only PDG associated with LOS (9 days (IQR 6-14) with anxiety diagnosis versus 8 days (IQR 5-12) with no anxiety diagnosis, p = 0.022). Multivariable modeling showed an independent association between anxiety diagnosis and increased LOS (OR 4.82 (1.25-25.23), p = 0.022). Anxiety was not associated with increased hospital cost or in-hospital mortality. CONCLUSIONS: This analysis demonstrates an independent effect of anxiety prolonging postoperative LOS after esophagectomy in the United States. These findings may influence perioperative care, patient expectations, and resource allocation.

Severe Chronic Obstructive Pulmonary Disease Is Not Associated With Complications After Navigational Bronchoscopy Procedures.

BACKGROUND: Electromagnetic navigational bronchoscopy (ENB) is a commonly used technique to obtain biopsies of peripheral pulmonary lesions. Little is known about risk factors for complications with this procedure. The aim of this study was to assess the complication rate associated with ENB and the relationship of complications to patient- and procedure-related factors. METHODS: Consecutive ENB procedures at an academic medical center between May 11, 2011, and September 11, 2015, were reviewed retrospectively. Preoperative characteristics, including pulmonary function, procedure characteristics, and the occurrence of complications, were recorded. RESULTS: In all, 361 procedures were performed on 341 patients. Complications occurred in 30 of 361 (8.3%), the most common of which was pneumothorax (27, 7.5%). Complications were not related to age, sex, American Society of Anesthesiologists grade, or pulmonary function test result. Patients with complications had longer procedure times (50 versus 73 minutes, p = 0.03), and had more interventional modalities used (2.4 versus 3.2, p = 0.001). Multiple logistic regression demonstrated that bronchoalveolar lavage was significantly associated with complications (odds ratio 6.40; 95% confidence interval: 1.68 to 24.3, p = 0.006). CONCLUSIONS: Electromagnetic navigational bronchoscopy is safe, and the rate of complications is not elevated among patients with poor lung function. Bronchoalveolar lavage performed during ENB was associated with elevated risk of complications and should be studied further.

Enucleation of esophageal leiomyoma by video-assisted thoracic surgery.

Thoracoscopic enucleation of benign distal esophageal leiomyoma is a minimally-invasive procedure that is comprised of four basic steps: (1) port placement and exposure, (2) dissection, (3) reconstruction, and (4) drain placement and closure. The procedure can be performed with minimal perioperative pain, excellent morbidity and mortality, and a high-degree of patient satisfaction. Some patients may experience mild dysphagia or dyspepsia in the postoperative interval, which is managed medically with proton pump inhibitors or surgically with antireflux repair.

Extrapleural pneumonectomy for malignant pleural mesothelioma.

Extrapleural pneumonectomy was introduced in the 1940s for the treatment of extensive infections of the lung and pleural space. Over the past 20 years, the extrapleural pneumonectomy technique has been modified and applied to the treatment of locally advanced malignant pleural mesothelioma, achieving substantial reductions in mortality. The current mortality rate of 3.4% at the Brigham and Women's Hospital has permitted us to expand our use of this operation to treat locally advanced lung cancer and thymoma. The extrapleural pneumonectomy technique consists of five basic steps: (1) Incision and exposure of the parietal pleura: (2) Dissection of the tumor and parietal pleura from the chest wall, diaphragm, and mediastinum: (3) Division and control of the pulmonary vessels and bronchus followed by lymph node dissection: (4) En bloc resection of the lung, pleura, pericardium, and diaphragm; (5) Reconstruction of the diaphragm and pericardium. Extrapleural pneumonectomy is a complex and challenging operation. Accompanied by a 60% minor and major complication rate, it requires a unique management approach to achieve 3.4% mortality. Primary contributing factors to the reduction in mortality include a reduced operative time of 3 h, refinements in operative technique, and improved selection of patients. The technique discussed below is the culmination of 20 years' experience with malignant pleural mesothelioma at the Brigham and Women's Hospital/Dana Farber Cancer Institute, Boston, MA USA.

Choices in the management of asymptomatic lung nodules in the elderly.

More than half of all lung cancer cases are diagnosed in patients older than 65 years of age. Risk of death after thoracotomy also increases over the age of 65. As a result, surgical intervention for lung cancer is often considered too risky in elderly patients, leaving the caregiver with a treatment dilemma when confronted with an abnormal radiographic finding. Advances in preoperative risk assessment, surgical and anesthetic techniques, radiation oncology, and locally ablative techniques have resulted in improved survival with a significant decrease in post-procedure mortality and morbidity for the aged population. On this basis, we believe treatment options for incidental pulmonary nodules found on chest roentgenograms should be discussed with patients and interventional work up pursued. It is no longer reasonable to deny elderly patients the benefits of surgical intervention simply on the basis of age. Every effort should be made to assess risk and optimize treatment for this large and growing segment of the population.
